Flexible Sigmoidoscopy


Sigmoidoscopy is the visual examination of the inside of the rectum and sigmoid colon using a lighted, flexible fiberoptioc or video endoscope.  The colon, or large intestine, is 5 to 6 feel long.  During a sigmoidoscopy, only the last 1 to 2 feet of the colon is examined.  This last part of the colon, just above the rectum is called the sigmoid colon.
